THOMAS FOREST COBLEB, OF LEAVENWORTH, KANSAS.

REFRIGERATOR.

Specification of Letters Patent. I .Patenfed Oct, 27, 191-1,

Application filed October 28, 1912. Serial No. 728,220.

To all whom. it may concern Be it known that I, Ti-ionAs It Conner, citizen of the United States, residing at Leavenworth, in the county of Leavenworth and" State of Kansas, have invented certain new and useful Improvements in Refrigerators, of which the followin is a specifi -ati'on.

My invention relates to new and useful improvements in refrigerators.

An object of my invention is to provide means for nmintaining a low temperature in the foodcontaining chest, said means consisting of a plurality of coils of'piping positioned'in the food chest itself, a constant stream of water being maintained through these coils. r

A. further ob'cct of my invention is to so construct and arrange these coils that they may be adjusted vertically within the food chest to position them adjacent supporting shelves therein, irrespective of the position of the shelves. And a still further object of my invention is to provide means. ineluding a pump for constantly supplying water to the coils.

ith these and other objects in view,-my invention will be more fully described, illustrated in the accompanying-drawings, and then specifically .pointedout in the claims which are attached to and form a part of this application.

In the drawings: Figure 1 is a front elevation of the improved refrigerator with the outer door open; Fig. 2 is a vertical section taken on the line 22 of Fig. 1'; Fig. 3

is a vertical section taken on the line of Fig.v 2, looking in the direction of the ar; rows; Fig. at is a horizontal section on the line 4-& of Fig. 9, also looking in the direction ofthe arrows.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The preferred embodiment of my invention consists primarily ofan outer casing 10 furnishing a reservoir for the cooling fluid and a housing for the inner casing or food holding chest proper 11 and alsoforthe pump mechanism, designated as a whole by thenumeral 1:2 which is employed for mainraining a proper circulation of the cooling fluid over the inner chest and through the cooling coils, as

The outer casing 10 is preferably formed of wood and is substantially rectangular in. shape as shown, being supported in slightly raised position by feet 13. The top or this outer casing is provided with .a hinged cover 1% and the entire casing,with the exception of the cover portion and the door opening 15, is provided'uith a lining 16 preferably formed of sheet metal with all joints soldered or otherwise rendered water tight. This lining is in all cases spaced from the outer wall and the spaces thus formed are filled \vith a )flclilll 17 of mineral wool, sawdust, or other suitable nonheat conduct ng material. As best shown in Fig. 2-of the drawings, the base portion of this lining'l i is inclined from the bot tom of the door opening downwardly and .rearwardly to cause all water falling upon the base to flow to the rear of the casing. The bottom liningat the rear of the casing is further lowered to provide a well or reservoir 18. torcceive the low r part of the pump mechanism, as will be hereinafter explained. This outer casing lO'is normally closed by a door 19 which is preferably mounted upon hinges and which closes the entire door opening. Mounted upon suitable supporting legs 20 within this outer casing, is the inner water tight casing 11 which forms the food receiving chest of the refrigerator. The bottom 21 of this inner casing is. spaced above the lining ofthe outer casing, as shown, while the-side walls 22 and rear wall of the inner casing are flared slightly at their lower edges, as shown at 23 tobreakthe fall of water flowing down the outer face of said walls and so prevent undue splashing from the same. The top 1% of the inner casing is inclined from the center toward the side walls of the front and rear walls of thecasing, as shown in Figs. 2 and 3 of the drawings and it will therefore be apparent that water flowing upon the top of the inner casing" will run evenly from the top and down the side and rear walls of the casing. lVater is prevented from flowing over the front wall of the casing ly a iflange 25-which completely surrounds the door opening '26 15 of the outer casing. The free edges of this flange are preferably soldered to the liningfof the outer casing to absolutely" prevent all leakage of water through the door opening and also to serve as abrace position.-

for'supportingthe inner casing or chest in vided-throughout their entire extent with a packing 27 of rubber or'other suitable material and the door opening is divided into sections by a transverse sash bar. 28'and vertical sash bars29, the-ends of which are socured in place by'catches 30,'t hese sash bars therefore being removable-to permit ready access to the chest for cleaning purposes. The, jambs of these sash bars are also pfovidedwith paclgingstrips 31 corresponding tQf the'p'a'cking strips 27 of the door jambs proper and a plurality of hinged doors 32 are'inounted'in the-door opening and co-act withfthe sash bars. to form a closure for the inher Leasing, these doors being provided- With latches 3 3, ofany' suitable type for securing the doors in closed position. It will therefore be apparent that any one of these doors maybe. opene'dto' permit access to a certain part ofthe chest. without opening the chest up wide-and exposing" its contents to the-Warmenoutside air; Itwi'l'l also. be ap parent that. allof the doors may beopened and thesashbars .relnov'edlto permit chang- "within the chest, as'desired; Positioned beneath each of the shelves 35, is a cooling coil 36, these coils. being connected by a telescopic pipe-member 37', the parts'o'f which fit closely to preventl'eakage, while at'the same time permitting the raising and lowering of the coils within the chest; The 10wer- 'mostcoil 36 is providedwith an outletpip'e 5-153 3.8 which extends through the" bottom 21 ofthechest and the topmost coil is provided with a second telescopic inlet pipe 39 which in'turn is connected to one end of a pipe 10, the opposite end of which leads through the central portionflof the top Ql of the chest,

- communicating. with a water distributing vessel 41; supported 'upon said'top and having its walls-perforatedupon all sides, as

Sho VnaFFlQ to provide passage for water from the vessel to the chest top from which it; will flow overfthe' side and rear-walls of the chest, as previously described. The pipe fl is provided with a'valve 40., By providing' the telescopicconnections above de-.. scribed,-'the -;posit1on' of the coils may be readily adjusted within the chest audwith respect to each. other to bring the same imiuedintely below the shelves, irrespectivifof j thef'positionof the shelves within the chest.

The outer casinglO is providedintermehe ja'mbs of the door opening 26 are proal ases diat'e its height with an intake pipe 43,

outer end of which is funnel shaped as 8,166; 1

and provided with a cut-offvalv'e 416. The water contained Within the reservoir is drained at. suitable intervals through the pipe 45 and colder, fresh water supplied in its place through the pipe 43.

In order to provide means for raising the water froin the well or reservoir 18 to the at 4A: and with an outlet pipe '45 leading from the lower portion of the reservoir 18 distributing vessel 11, I-provide bearings 45? inwhich is journaled .a shaft 48 carrying a sprocket gear 49 and a second shaft50 extending transversely of the rear portion of the refrigerator and jo-urnaled in bearingsformed in the walls of the'outer' casing.

Keyed upon this second shaft, is a sprocket gear 51 and a pinion 52.. Trained about the sprocket gears 49 and 51, is a pump chain 53 having the usual water lifting cups 54,

the chain at one side passing through the vertically disposed pump cylinder which is supported in place by brackets 56 extend- 1 ing from the chest 11. The pump thus I formed ispositioned at the rear of.,the chest and centrally between the sides thereof, as

best shown in Fig. 4 ofthe drawings. Lead 1 ing from the upper end ofr'the pump cylinder 55, is a spout 57 which. discharges in the distributing vessel 41.

Brackets 58 :carried by! the upper portion of the rear wall of the chest 11, support a shelf 59 carrying bearings 60 in which are journaled parallel shafts 61 and 62,0119 end.

of the first 'mentioned shaft extending through theouter Wall of the refrigerator and having a squared-terminal can) receive ioo a hand crank 64. Keyed upon the shaft 61,

is algear 65 which meshes 'Wliill a pinion 66 keyed upon the shaft 62. and a gear 67 also keyed upon the shaft 62. meshes with thepinion 52 of the pump shaft 50. A heavy coiled spring 68' is wound about the shaft 61,

one'end of the spring being secured to the shaft, while the opposite end-is secured'to the shelf 59. 1 v

From'the foregoing description, ,it will be apparent that the shaft 61 maybe rotated by the hand crank 64: to wind the spring 68, and that the power derived from this spring will be transmitted through the gears" above 4 described to rotate-the pump shaft 60 and so operate the pump.- I The'spring 68, gears and. pump should be so related that the spring when once wound will drive the pump at a suitable rate .of .speedfor at least twenty-four hours. 1 1

.In order to provide means for starting the pump, after wind ng the spring, in case its initial strength is not sufficient to o-ver-..- come theinertia of the :pump' .mechanism,-I' have extended one end of'the pump shaft 50 beyond the outer casingof the refrigerator and provided it. with a squared terminal 69 also ada ted to receive the hand crank 64, thus provi ing means for starting the pump /ma-nu ally. i

A shield 70 of sheet metal, is preferably rovided'about the gears to protect the same rom moisture and also to prevent any dripping of oil fromithe gears to the water contained in the well or reservoir.

From the foregoing description, taken in connection with the drawings, the construction of my improved refrigerator will be readily understood as will also the operation 1 of the pump and its mechanism in maintaining the required circulation of water through the cooling coil and about the food holding chest of the refrigerator.

It will of course be understood that minor changes in details of construction may be made, if desired, without in the slightest degree departing from the spirit of my invention.

Having thus described the invention, what is claimed as new-is: A

1. A refrigerator including a casing, a food chest positioned within the casing, a reservoir receiving the bottom portion of the chest and adapted to contain a supply of Water, a cooling pipe leading through the chest at the top and bottom thereof and arranged to discharge into the reservoir, and means for supplying the water to the upper end of the ipe from the reservoir.
